Hexagon head bolt DIN 931 / ISO 4014, M 16x70, hexagon 24 mm, thread length 38 mm, steel 10.9, plain

More highly preloaded joints need a defined shank cross section. This hexagon head bolt M 16x70 to DIN 931 in steel of property class 10.9, plain and black offers 32 mm of plain shank and limits the thread to 38 mm. Tightening takes place on the hexagon with 24 mm across flats at a head height of 10.0 mm. The surface is plain and black.

Advantages

• Property class 10.9, plain and black, suited to more highly preloaded joints in protected indoor positions.
• Width across flats of 24 mm to DIN 931 and 24 mm to ISO 4014, both figures are stated and therefore known before assembly.
• Plain shank of 32 mm within 70 mm of total length, which places the shear plane in the full shank cross section instead of the thread.
• Thread length of 38 mm to DIN 931, sufficient for a nut and a washer in size M 16.

Applications

The bolt is dimensioned to DIN 931 and ISO 4014. The width across flats is 24 mm to DIN 931 and 24 mm to ISO 4014. The material is steel of property class 10.9, plain and black.
